FIELD

The disclosure is directed to devices providing at least one opticalconnection port along with methods for making the same. Morespecifically, the disclosure is directed to devices such as multiportscomprising a keyed-connection port and a securing feature associatedwith the connection port for securing an optical connector along withmethods of making the same.

BACKGROUND

Optical fiber is increasingly being used for a variety of applications,including but not limited to broadband voice, video, and datatransmission. As bandwidth demands increase optical fiber is migratingdeeper into communication networks such as in fiber to the premisesapplications such as FTTx, 5G and the like. As optical fiber extendeddeeper into communication networks the need for making robust opticalconnections in outdoor applications in a quick and easy manner wasapparent. To address this need for making quick, reliable, and robustoptical connections in communication networks hardened fiber opticconnectors such as the OptiTap® plug connector were developed.

Multiports were also developed for making an optical connections withhardened connectors such as the OptiTap. Prior art multiports have aplurality of receptacles mounted through a wall of the housing forprotecting an indoor connector inside the housing that makes an opticalconnection to the external hardened connector of the branch or dropcable.

Illustratively, FIG. 1 shows a conventional fiber optic multiport 1having an input fiber optic cable 4 carrying one or more optical fibersto indoor-type connectors inside a housing 3. The multiport 1 receivesthe optical fibers into housing 3 and distributes the optical fibers toreceptacles 7 for connection with a hardened connector. The receptacles7 are separate assemblies attached through a wall of housing 3 of themultiport 1. The receptacles 7 allow mating with hardened connectorsattached to drop or branching cables (not shown) such as drop cables for“fiber-to-the-home” applications. During use, optical signals passthrough the branch cables, to and from the fiber optic cable 4 by way ofthe optical connections at the receptacles 7 of multiport 1. Fiber opticcable 4 may also be terminated with a fiber optic connector 5.Multiports 1 allowed quick and easy deployment for optical networks.

Although, the housing 3 of the prior art multiport 1 is rugged andweatherable for outdoor deployments, the housings 3 of multiport 1 arerelatively bulky for mounting multiple receptacles 7 for the hardenedconnector on the housing 3. Receptacles 7 allow an optical connectionbetween the hardened connector such as the OptiTap male plug connectoron the branch cable with a non-hardened connector such as the SCconnector disposed within the housing 3, which provides a suitabletransition from an outdoor space to a protected space inside the housing3.

Receptacle 7 for the OptiTap connector is described in further detail inUS Pat. No. 6,579,014. As depicted in US 6,579,014, the receptacleincludes a receptacle housing and an adapter sleeve disposed therein.Thus, the receptacles for the hardened connector are large and bulky andrequire a great deal of surface array when arranged in an array on thehousing 3 such as shown with multiport 1. Further, conventional hardenedconnectors use a separate threaded or bayonet coupling that requiresrotation about the longitudinal axis of the connector and room forgrabbing and rotating the coupling by hand when mounted in an array onthe housing 3.

Consequently, the housing 3 of the multiport 1 is excessively bulky. Forexample, the multiport 1 may be too boxy and inflexible to effectivelyoperate in smaller storage spaces, such as the underground pits orvaults that may already be crowded. Furthermore, having all of thereceptacles 7 on the housing 3, as shown in FIG. 1 , requires sufficientroom for the drop or branch cables attached to the hardened connectorsattached to the multiport 1. While pits can be widened and largerstorage containers can be used, such solutions tend to be costly andtime-consuming. Network operators may desire other deploymentapplications for multiports 1 such as aerial, in a pedestal or mountedon a facade of a building that are not ideal for the prior artmultiports 1 for numerous reasons such as congested poles or spaces orfor aesthetic concerns.

Other multiports designs have been commercialized to address thedrawbacks of the prior art multiports depicted in FIG. 1 . By way ofexplanation, US 2015/0268434 discloses multiports 1′ having one or moreconnection ports 9 positioned on the end of extensions 8 that projectfrom the housing of the multiport 1′ such as depicted in FIG. 2 .Connection ports 9 of multiport 1′ are configured for mating directlywith a hardened connector (not shown) such as an OptiTap without theneed to protect the receptacle 7 within a housing like the prior artmultiport 1 of FIG. 1 .

Although, these types of multiport designs such as shown in FIG. 2 anddisclosed in US 2015/0268434 allow the device to have smaller footprintsfor the housing 3′, these designs still have concerns such as the spaceconsumed by the relatively large ports 9 and associated spacerequirements of optical connections between the ports and hardenedconnector of the drop cables along with organizational challenges.Simply stated, the ports 9 on the extensions 8 of the multiport 1′ andthe optical connections between ports 9 and hardened connector occupysignificant space at a location a short distance away from the multiporthousing 3′ such as within a buried vault or disposed on a pole. In otherwords, a cluster of optical ports 9 of multiport 1′ are bulky or occupylimited space. The conventional hardened connectors used with multiport1′ also use a separate threaded or bayonet coupling that requiresrotation about the longitudinal axis of the connector along withsufficient space for grabbing and rotating the coupling means by hand.Further, there are aesthetic concerns with the prior art multiports 1′as well.

Consequently, there exists an unresolved need for multiports that allowflexibility for the network operators to quickly and easily make opticalconnections in their optical network while also addressing concernsrelated to limited space, organization, or aesthetics.

DETAILED DESCRIPTION

Reference will now be made in detail to the embodiments of thedisclosure, examples of which are illustrated in the accompanyingdrawings. Whenever possible, like reference numbers will be used torefer to like components or parts.

The concepts for the devices disclosed herein are suitable for providingat least one optical connection to the device for indoor, outdoor orother environments as desired. Generally speaking, the devices disclosedand explained in the exemplary embodiments are multiports, but theconcepts disclosed may be used with any suitable device as appropriate.As used herein, the term “multiport” means any device comprising atleast one connection port for making an optical connection and asecuring feature associated with the at least one connection port. Byway of example, the multiport may be any suitable device having at leastone optical connection such as a passive device like an optical closure(hereinafter “closure”) or an active device such as a wireless devicehaving electronics for transmitting or receiving a signal.

The concepts disclosed advantageously allow compact form-factors fordevices such as multiports comprising at least one connection port and asecuring feature associated with the connection port. The concepts arescalable to any suitable count of connection ports on a device in avariety of arrangements or constructions. The securing featuresdisclosed herein for devices engage directly with a portion of connectorwithout conventional structures like prior art devices that require theturning of a coupling nut, bayonet or the like.. As used herein,“securing feature” excludes threads and features that cooperate withbayonets on a connector. Thus, the devices disclosed may allowconnection ports to be closely spaced together and may result in smalldevices since the room needed for turning a threaded coupling nut orbayonet is not necessary. The compact form-factors may allow theplacement of the devices in tight spaces in indoor, outdoor, buried,aerial, industrial or other applications while providing at least oneconnection port that is advantageous for a robust and reliable opticalconnection in a removable and replaceable manner. The disclosed devicesmay also be aesthetically pleasing and provide organization for theoptical connections in manner that the prior art multiports cannotprovide.

The devices disclosed are simple and elegant in their designs. Thedevices disclosed comprise at least one connection port and a securingfeature associated with the connection port that is suitable forretaining an external fiber optic connector received by the connectionport. The connection port may include a keying portion that cooperateswith a key on a complimentary external fiber optic connector to inhibitdamage to the connection port by inhibiting the insertion of anon-compliant connector. The keying portion may also aid the user duringblind insertion of the connector into the connection port of the deviceto determine the correct rotational orientation with respect to theconnection port when a line of sight is not possible or practical foralignment.

Unlike prior art multiports, the concepts disclosed advantageously allowthe quick and easy connection and retention by inserting the fiber opticconnectors directly into the connection port of the device without theneed or space considerations for turning a threaded coupling nut orbayonet for retaining the external fiber optic connector. Generallyspeaking, the securing features disclosed for use with devices hereinmay comprise one or more components with at least one componenttranslating for releasing or securing the external fiber optic connectorto the device. As used herein, the term “securing feature” excludesthreaded portions or features for securing a bayonet disposed on aconnector.

Since the connector footprint used with the devices disclosed does notrequire the bulkiness of a coupling nut or bayonet, the fiber opticconnectors used with the devices disclosed herein may be significantlysmaller than conventional connectors used with prior art multiports.Moreover, the present concepts for connection ports on devices allows anincreased density of connection ports per volume of the shell orincreased port width density since there is no need for accessing andturning the coupling nut or bayonets by hand for securing a fiber opticconnector like the prior art multiports.

The devices disclosed comprise a securing feature for directly engagingwith a suitable portion of a connector housing of the external fiberoptic connector or the like for securing an optical connection with thedevice. Different variations of the concepts are discussed in furtherdetail below. The structure for securing the fiber optic connectors inthe devices disclosed allows much smaller footprints for both thedevices and the fiber optic connectors along with a quick-connectfeature. Devices may also have a dense spacing of connection ports ifdesired. The devices disclosed advantageously allow a relatively denseand organized array of connection ports in a relatively smallform-factor while still being rugged for demanding environments. Asoptical networks increase densifications and space is at a premium, therobust and small-form factors for devices such as multiports, closuresand wireless devices disclosed herein becomes increasingly desirable fornetwork operators.

The concepts disclosed herein are suitable for optical distributionnetworks such as for Fiber-to-the-Home and 5G applications, but areequally applicable to other optical applications as well includingindoor, automotive, industrial, wireless, or other suitableapplications. Additionally, the concepts disclosed may be used with anysuitable fiber optic connector footprint that cooperates with thesecuring feature of the device. Various designs, constructions, orfeatures for devices are disclosed in more detail as discussed hereinand may be modified or varied as desired.

The devices disclosed may locate the at least one connection port 236 indifferent portions or components of the device as desired using thedisclosed concepts. The concepts are shown and described with a device200 having 4- connection ports that are optically connected to an inputport arranged in an array on one end of the device, but otherconfiguration are possible such as connection ports or input ports onboth ends, an express port, a pass-through port or the like. FIGS. 3-32show the construction and features for a first explanatory multiport,and FIGS. 33-47 show the construction of a second explanatory multiport200 similar to the first multiport 200. Although, these concepts aredescribed with respect to multiports the concepts may be used with anyother suitable devices such as wireless devices (FIG. 49 ), closures(FIG. 50 ) or other suitable devices.

FIGS. 3 and 4 respectively depict top and bottom perspective views ofthe first explanatory multiport 200 comprising at least one connectionport 236. The Generally speaking, devices such as multiport 200 comprisea shell 210 comprising a body 232 and one or more connection ports 236disposed on a first end or portion 212 of multiport 200. The connectionports 236 or input port 260 are configured for receiving and retainingsuitable external fiber optic connectors 10 (FIG. 39 ) for makingoptical connections with the multiport 200.

Connection ports 236 each comprises a respective optical connectoropening 238 extending from an outer surface 234 of the multiport 200into a cavity 216 of the multiport 200 and defining a portion of aconnection port passageway 233. By way of explanation, at least oneconnection port 236 is molded as a portion of shell 210. At least onesecuring feature 310 is associated with the connection port passageway233 for cooperating with the external fiber optic connector 10. Thesecuring feature 310 may translate for releasing or securing theexternal fiber optic connector 10. Multiport 200 of FIGS. 3 and 4 alsocomprises an input port 260 that is similar to the connection ports 236.As shown, the connection ports 236 or input port 260 may comprise amarking indicia such as an embossed number or text, but other markingindicia are also possible. For instance, the marking indicia may be onthe securing feature 310 such as text or the securing features may becolor-coded to indicate fiber count, input or output for the associatedconnection port or input port.

The concepts disclosed use a securing feature resilient member 310RM forbiasing a portion of the securing feature 310 as discussed herein.Multiports 200 disclosed use one or more modular adapter sub-assemblies310SA (FIGS. 9-12 ) disposed within a shell for a scalable form-factorfor manufacturing similar devices with different port counts. The shellcomprises one or more connection ports and device comprises one or morerespective securing features 310 cooperating with the connection portsfor providing quick and easy optical connectivity with a robust andreliable design that is intuitive to use.

Optical connections to the devices are made by inserting one or moresuitable external fiber optic connectors into respective connection portpassageways 233 as desired. Specifically, the connection port passageway233 is configured for receiving a suitable external fiber opticconnector (hereinafter connector) of a fiber optic cable assembly(hereinafter cable assembly). Connection port passageway 233 isassociated with a securing feature 310 for retaining (e.g., securing)the connector in the multiport 200 for making an optical connection. Thesecuring feature 310 advantageously allows the user to make a quick andeasy optical connection at the connection port 236 of multiport 200. Thesecuring feature 310 may also operate for providing a connector releasefeature when actuated.

Specifically, the connector may be retained within the respectiveconnection port 236 of the device by pushing and fully-seating theconnector within the connection port 236. To release the connector fromthe respective connection port 236, the securing feature 310 is actuatedby pushing inward and releasing the securing feature 310 from thelocking feature 20L on the external connector housing 20 (FIG. 39 ) andallowing the connector to be removed from the connection port 236.Stated another way, the at least one securing feature 310 is capable ofreleasing the connector when a portion of the securing feature 310translates within a portion of a securing feature passageway 245. Thefull insertion and automatic retention of the connector mayadvantageously allow one-handed installation of the connector by merelypushing the connector into the connection port 236. The devicesdisclosed accomplish this connector retention feature uponfull-insertion by biasing the securing feature to a retain position.However, other modes of operation for retaining and releasing theconnector are possible according to the concepts disclosed. Forinstance, the securing feature 310 may be designed to require actuationfor inserting the connector; however, this may require a two-handedoperation.

Securing feature 310 may be designed for holding a minimum pull-outforce for the connector. In some embodiments, the pull-out force may beselected to release the connector before damage is done to the device orthe connector. By way of example, the securing feature 310 associatedwith the connection port 236 may require a pull-out force of about 50pounds (about 220N) before the connector would release. Likewise, thesecuring feature 310 may provide a side pull-out force for connector forinhibiting damage as well. By way of example, the securing feature 310associated with the connection port 236 may provide a side pull-outforce of about 25 pounds (about 110N) before the connector wouldrelease. Of course, other pull-out forces such as 75 pounds (about 330N)or 100 (about 440N) pounds are possible along with other side pull-outforces.

FIGS. 3 and 4 depict that shell 210 is formed by a first portion 210Aand a second portion 210B, but other constructions are possible forshell 210 using the concept disclosed. Multiport 200 or devices maycomprise mounting features that are integrally formed in the shell 210or that are separate components attached to shell 210 for mounting thedevice as depicted in FIGS. 3 and 4 . By way of example, shell 210depicts mounting features 210MF disposed near first and second ends 212,214 of shell 210. Mounting feature 210MF adjacent the first end 212 ofmultiport 200 is a mounting tab 298 attached to shell 210, and themounting feature 210MF adjacent the second end 214 is a through holewith a support 210S. Details of mounting tab will be discuss in furtherdetail with respect to FIG. 15 and, and details of support 210S will bediscussed in further detail with respect to FIG. 8 . However, mountingfeatures 210MF may be disposed at any suitable location on the shell 210or connection port insert 230. For instance, multiport 200 also depictsa plurality of mounting features 210MF integrally-formed on shell 210and configured as passageways disposed on the lateral sides. Thus, theuser may simply use a fastener such as a zip-tie threaded thru theselateral passageways for mounting the multiport 200 to a wall or pole asdesired. Shell 210 may also include one or more notches 210N on thebottom side for aiding in securing the device to a round pole or thelike as shown in FIG. 4 .

FIGS. 5-7 depict various cross-sections through a connection portpassageway 233 showing the internal construction of multiport 200, andFIG. 8 is a partially exploded view of multiport 200 showing the opticalfibers 250 that optically connect the connection ports 236 with theinput port 260 inside the device. As depicted in FIG. 8 , multiport 200comprises a shell 210 comprising at least one connection port 236, and amodular adapter sub-assembly 310SA as discussed in further detail herein

FIGS. 5-7 depicts the multiport 200 comprising at least one connectionport 236 extending from an outer surface 234 of the multiport 200 into acavity 216 of the multiport 200 and defining a connection portpassageway 233. Multiport 200 also comprises at least one securingfeature 310 associated with the connection port passageway 233.Multiport 200 also comprises at least one securing feature passageway245 for receiving a portion of the securing feature 310. As depicted,the securing feature passageways 245 extend from the outer surface 234of multiport 200 to cooperate with the respective connection portpassageways 233 of the multiport 200. Multiport 200 also comprises aplurality of adapters 230A for receiving respective rear connectors 252in alignment with the respective connection port 236 for making theoptical connection with the external fiber optic connector.

The securing features 310 disclosed herein may take many differentconstructions or configurations as desired such as being formed as asingle component or a plurality of components. Securing features 310 maybe biased by a resilient member 230 RM. Furthermore, the securingfeatures 310 or portions of securing features 310 may be constructed asa portion of a modular adapter sub-assemblies 310SA such as shown inFIGS. 9-12 for easy assembly of the multiport 200. Moreover, the modularsub-assemblies 230SA advantageously allow the mating components for eachconnection port 236 to move or “float” independently of other matingcomponents relative to the shell 210 for the other connection ports forpreserving optical performance. “Float” means that the adapter 230A canhave slight movement in the X-Y plane for alignment, and may beinhibited from over-traveling in the Z-direction along the axis ofconnector insertion so that suitable alignment may be made betweenmating connectors, which may include a biasing spring for allowing somedisplacement of the adapter 230A with a suitable restoring forceprovided by the spring.

Generally speaking, the devices disclosed comprise at least oneconnection port 236 defined by an optical connector opening 238extending into a cavity 216 of the device 200, 500, 700 along with asecuring feature 310 associated with the connection port 236.

As best shown in FIGS. 6 and 7 , securing feature 310 is biased to aretain position. Specifically, the securing feature 310 is biased in anupward direction using a securing feature resilient member 310RM. Morespecifically, securing feature resilient member 310RM is disposedbeneath securing feature 310 for biasing to a normally retain positionfor the securing feature 310 where the locking feature 310L is disposedin the connection port passageway 233.

As best depicted in FIGS. 6 and 7 , a portion of actuator 310A isdisposed within a portion of the securing feature passageway 245 andcooperates with the securing member 310M of the respective securingfeature. Consequently, a portion of securing feature 310 (i.e., theactuator 310A) is capable of translating within a portion of thesecuring feature passageway 245. Actuator 310A comprises a finger 310Ffor seating within a rim 310R of securing member 310M for transferringforces to the same. As depicted, a sealing feature 310S is disposed onthe securing feature 310. Sealing feature 310S provides a seal between aportion of the securing feature 310 and the securing feature passageway245 to inhibit dirt, dust and debris from entering the device. As shown,the sealing feature 310S is disposed within a groove of actuator 310A.

In this embodiment, the securing feature 310 comprises a bore 310B thatis aligned with the least one connection port passageway 233 whenassembled as best shown in FIG. 7 . Bore 310B is sized for receiving asuitable connector therethrough for securing the same for opticalconnectivity. Bores or openings through the securing feature 310 mayhave any suitable shape or geometry for cooperating with its respectiveconnector. As used herein, the bore may have any suitable shape desiredincluding features on the surface of the bore for engaging with aconnector. Bore 310B is disposed on the securing member 310M in thisembodiment.

In some embodiments, a portion of the securing feature 310 is capable ofmoving to an open position when inserting a suitable connector 10 intothe connection port passageway 233. When the connector 10 isfully-inserted into the connector port passageway 233, the securingfeature 310 such as the securing member 310M is capable of moving to theretain position automatically. Consequently, the connector 10 is securedwithin the connection port 236 by securing feature 310 without turning acoupling nut or a bayonet like the prior art multiports. Stated anotherway, the securing feature 310 translates from the retain position to anopen position as a suitable connector 10 is inserted into the connectionport 236. The securing feature passageway 245 is arranged transverselyto a longitudinal axis LA of the multiport 200, but other arrangementsare possible. Other securing features may operate in a similar manner,but use an opening instead of a bore that receives the connectortherethrough.

FIGS. 6 and 7 depict securing feature 310 comprising a locking feature310L. Locking feature 310L cooperates with a portion of the connector 10when it is fully-inserted into the connection port 236 for securing thesame. As best shown in FIG. 39 , the connector housing 20 of connector10 may have a cooperating geometry that engages the locking feature 310Lof securing feature 310. In this embodiment, locking feature 310Lcomprises a ramp 310RP. The ramp is integrally formed at a portion ofthe bore 310B with the ramp angling up when looking into the connectionport 236. The ramp allows the connector to push and translate thesecuring feature 310 downward against the securing feature resilientmember 310RM as the connector is inserted in the connection port 236 asshown. Ramp may have any suitable geometry. Once the locking feature310L of the securing feature 310 is aligned with the cooperatinggeometry of the locking feature 20L of connector, then a portion of thesecuring feature 310 translates so that the locking feature 310L engagesthe locking feature of connector.

Locking feature 310L comprises a retention surface 310RS. In thisembodiment, the back-side of the ramp of locking feature 310L forms aledge that cooperates with complimentary geometry on the connectorhousing of connector. However, retention surface 310RS may havedifferent surfaces or edges that cooperate for securing connector forcreating the desired mechanical retention. For instance, the retentionsurface 310RS may be canted or have a vertical wall for tailoring thepull-out force for the connection port 236. However, other geometriesare possible for the retention surface 310RS. Additionally, theconnection port 236 has a sealing location at a connection portpassageway sealing surface with the connector that is located closer tothe optical connector opening 238 at the outer surface 234 than thesecuring feature 310 or locking feature 310L. In other words, connectionport 236 has connection port passageway sealing surface for theconnector disposed at a distance from the optical connector opening 238and the locking feature 310L and securing feature 310 are disposed at adistance further into the connection port passageway 233 than distancewhere the connector sealing occurs.

Generally speaking, the connection port passageways 233 may beconfigured for the specific connector intended to be received in theconnection port 236. Likewise, the connection port passageways 233should be configured for receiving the specific rear connector 252 formating and making an optical connection with the connector 10.

The device 200 also comprises at least one adapter 230A aligned with therespective connection port 236 or connection port passageway 233.Adapter 230A and other components are a portion of the modularsub-assembly 310SA as depicted in FIGS. 9-12 . Adapter 230A is suitablefor securing a rear connector 252 thereto for aligning the rearconnector 252 with the connection port 236. One or more optical fibers250 (FIG. 8 ) may be routed from the connection port 236 toward an inputconnection port 260 of the multiport 200. For instance, the rearconnector 252 may terminate the optical fiber 250 for optical connectionat connection port 236 and route the optical fiber 250 for opticalcommunication with the input connection port 260.

A plurality of rear connectors 252 are aligned with the respectiveconnector port passageways 233 within the cavity 216 of the multiport200. The rear connectors 252 are associated with one or more of theplurality of optical fibers 250. Each of the respective rear connectors252 aligns and attaches to a structure such as the adapter 230A or otherstructure related to the connection port passageway 233 in a suitablematter. The plurality of rear connectors 252 may comprise a suitablerear connector ferrule 252F as desired and rear connectors 252 may takeany suitable form from a simple ferrule that attaches to a standardconnector type inserted into an adapter. By way of example, rearconnectors 252 may comprise a resilient member for biasing the rearconnector ferrule 252F or not. Additionally, rear connectors 252 mayfurther comprise a keying feature.

The rear connectors 252 shown in FIGS. 5-7 have a SC footprint, butother connectors are possible. If SC connectors are used as the rearconnector 252 they have a keying feature 252K that cooperates with thekeying feature of adapter 230A. Additionally, adapters 230A comprise aretention feature (not numbered) for seating the adapters 230A in thedevice adjacent to the connection port passageway 233.

As best shown in FIGS. 7 and 15 , the connection port passageway 233 maycomprises a keying portion 233KP disposed forward of the securingfeature 310 in connection port passageway. As shown, the keying portion233KP is an additive keying portion to the primitive geometric roundshape of the connection port passageway 233 such as a male key that isdisposed forward of the securing feature in the connection portpassageway 233. However, the concepts for the connection ports 236 ofdevices may be modified for different connector designs.

Adapters 230A are secured to an adapter body 255 using retainer 240.Adapters 230A may be biased using a resilient member 230RM as shown.Rear connectors 252 may take any suitable form and be aligned for matingwith the connector secured with the connection ports 236 in any suitablemanner. Adapters 230A may comprise latch arms for securing respectiverear connectors therein.

Multiport 200 may have the input connection port 260 disposed in anysuitable location. As used herein, “input connection port” is thelocation where external optical fibers are received or enter the device,and the input connection port does not require the ability to make anoptical connection as discussed below. By way of explanation, multiport200 may have the input connection port 260 disposed in an outboardposition of the array of connection ports 236, on another side of themultiport, or disposed in a medial portion of array of connection ports236 as desired.

FIG. 8 shows a partially exploded view of multiport 200 of FIGS. 3 and 4. Multiport 200 comprises a shell 200, at least one connection port 236,and a plurality of modular adapter sub-assemblies 310SA. Multiport 200has one or more optical fibers 250 routed from the one or moreconnection ports 236 toward an input connection port 260 in a suitablefashion inside cavity 216 as depicted. In this embodiment, the rearconnectors 252 are attached to optical fibers 250 that are routingthrough an optical splitter 275 (hereinafter “splitter(s)”) for opticalcommunication with the optical fiber 250 in optical communication withthe input port 260. As shown, the modular adapter sub-assembly 310SA forthe input connection port 260 is disposed in second portion 210B ofshell 210.

Optical fibers 250 are routed from one or more of the plurality ofconnection ports 236 toward an input connection port 260 for opticalcommunication within the multiport 200. Consequently, the inputconnection port 260 receives one or more optical fibers and then routesthe optical signals as desired such as passing the signal through 1:1distribution, routing through an optical splitter or passing opticalfibers through the multiport. Splitters 275 such as shown in FIG. 8allow a single optical signal to be split into multiple signals such as1xN split, but other splitter arrangements are possible such as a 2xNsplit. For instance, a single optical fiber may feed input connectionport 260 and use a 1x8 splitter within the multiport 200 to allow eightconnector ports 236 for outputs on the multiport 200. The inputconnection port 260 may be configured in a suitable manner with any ofthe multiports 200 disclosed herein as appropriate such as asingle-fiber or multi-fiber port. Likewise, the connection ports 236 maybe configured as a single-fiber port or multi-fiber port. For the sakeof simplicity and clarity in the drawings, all of the optical fiberpathways may not be illustrated or portions of the optical fiberpathways may be removed in places so that other details of the designare visible.

Additionally, the multiports or shells 210 may comprise at least onesupport 210S or fiber guide for providing crush support for themultiport and resulting in a robust structure. As depicted in FIG. 8 ,multiport 200 may comprise a support 210S configured as a support insertthat fits into shell 210. Support 210S has a bore therethrough and mayact as a mounting feature for the use to a fastener to mount themultiport 200. Consequently, the support 210S carries the majority ofany crushing forces that may be applied by the fastener and inhibitsdamage to the shell 210. Support 210S may also be located and attachedto the shell at a location outside of the sealing interface between thefirst portion 210A and the second portion 210B of shell 210.

FIG. 7 also depicts a detailed sectional view of the interlockingfeatures between the first portion 210A and the second portion 210B ofthe shell 210. Specifically, portions of the multiport may have a tongue210T and groove 210G construction for alignment or sealing of thedevice.

Any of the multiports 200 disclosed herein may optionally beweatherproof by appropriately sealing seams of the shell 210 using anysuitable means such as gaskets, O-rings, adhesive, sealant, welding,overmolding or the like. To this end, multiport 200 or devices may alsocomprise a sealing element 290 disposed between the first portion 210Aand the second portion 210B of the shell 210. The sealing element 290may cooperate with shell 210 geometry such as respective grooves 210G ortongues 210T in the shell 210. Grooves or tongue may extend about theperimeter of the shell 210. By way of explanation, grooves 210G mayreceive one or more appropriately sized O-rings or gaskets 290A forweatherproofing multiport 200, but an adhesive or other material may beused in the groove 210G. By way of example, the O-rings are suitablysized for creating a seal between the portions of the shell 210. By wayof example, suitable O-rings may be a compression O-ring for maintaininga weatherproof seal. Other embodiments may use an adhesive or suitablewelding of the materials for sealing the device. If welding such asultra-sonic or induction welding of the shell is used a special sealingelement 290 may be used as known in the art. If the multiport 200 isintended for indoor applications, then the weatherproofing may not berequired.

As shown in FIG. 8 , multiport 200 comprises a single input opticalfiber of the input connection port 260 is routed to a 1:4 splitter 275and then each one of the individual optical fibers 250 from the splitteris routed to each of the respective rear connector 252 of the fourconnection ports 236 for optical connection and communication within themultiport. Input connection port 260 may be configured in any suitableconfiguration for the multiports disclosed as desired for the givenapplication. Examples of input connection ports 260 include beingconfigured as a single-fiber input connection, a multi-fiber inputconnector, a tether input that may be a stubbed cable or terminated witha connector or even one of the connection ports 236 may function as anpass-through connection port as desired.

By way of explanation for multi-fiber ports, two or more optical fibers250 may be routed from one or more of the plurality of connection ports236 of the multiport 200 disclosed herein. For instance, two opticalfibers may be routed from each of the four connection ports 236 ofmultiport 200 toward the input connection port 260 with or without asplitter such as single-fiber input connection port 260 using a 1:8splitter or by using an eight-fiber connection at the input connectionport 260 for a 1:1 fiber distribution. To make identification of theconnection ports or input connection port(s) easier for the user, amarking indicia may be used such as text or color-coding of themultiport, color codes on the actuator 310A, or marking the input tether(e.g. an orange or green polymer) or the like.

Other configurations are possible besides an input connection port 260that receives a connector 10. Instead of using a input connection portthat receives a connector 10, multiports 200 may be configured forreceiving an input tether 270 attached to the multiport at the inputconnection port 260 such as represented in FIGS. 40A and 40B.

The concepts disclosed allow relatively small multiports 200 having arelatively high-density of connections along with an organizedarrangement for connectors 10 attached to the multiports 200. Shellshave a given height H, width W and length L that define a volume for themultiport as depicted in FIG. 3 . By way of example, shells 210 ofmultiport 200 may define a volume of 800 cubic centimeters or less,other embodiments of shells 210 may define the volume of 400 cubiccentimeters or less, other embodiments of shells 210 may define thevolume of 100 cubic centimeters or less as desired. Some embodiments ofmultiports 200 comprise a connection port insert 230 having a port widthdensity of at least one connection port 236 per 20 millimeters of widthW of the multiport 200. Other port width densities are possible such as15 millimeters of width W of the multiport. Likewise, embodiments ofmultiports 200 may comprise a given density per volume of the shell 210as desired.

The concepts disclosed allow relatively small form-factors formultiports as shown in Table 1. Table 1 below compares representativedimensions, volumes, and normalized volume ratios with respect to theprior art of the shells (i.e., the housings) for multiports having 4, 8and 12 ports as examples of how compact the multiports of the presentapplication are with respect to convention prior art multiports.Specifically, Table 1 compares examples of the conventional prior artmultiports such as depicted in FIG. 1 with multiports having a lineararray of ports. As depicted, the respective volumes of the conventionalprior art multiports of FIG. 1 with the same port count are on the orderof ten times larger than multiports with the same port count asdisclosed herein. By way of example and not limitation, the multiportmay define a volume of 400 cubic centimeters or less for 12-ports, oreven if double the size could define a volume of 800 cubic centimetersor less for 12-ports. Multiports with smaller port counts such as4-ports could be even smaller such as the shell or multiport defining avolume of 200 cubic centimeters or less for 4-ports, or even if doublethe size could define a volume of 200 cubic centimeters or less for4-ports. Devices with sizes that are different will have differentvolumes form the explanatory examples in Table 1 and these othervariations are within the scope of the disclosure. Consequently, it isapparent the size (e.g., volume) of multiports of the presentapplication are much smaller than the conventional prior art multiportsof FIG. 1 . In addition to being significantly smaller, the multiportsof the present application do not have the issues of the conventionalprior art multiports depicted in FIG. 2 . Of course, the examples ofTable 1 are for comparison purposes and other sizes and variations ofmultiports may use the concepts disclosed herein as desired.

One of the reasons that the size of the multiports may be reduced insize with the concepts disclosed herein is that the connectors thatcooperate with the multiports have locking features that are integratedinto the housing 20 of the connectors 10. In other words, the lockingfeatures for securing connector are integrally formed in the housing ofthe connector, instead of being a distinct and separate component like acoupling nut of a conventional hardened connector used with conventionalmultiports. Conventional connectors for multiports have threadedconnections that require finger access for connection and disconnecting.By eliminating the threaded coupling nut (which is a separate componentthat must rotate about the connector) the spacing between conventionalconnectors may be reduced. Also eliminating the dedicated coupling nutfrom the conventional connectors also allows the footprint of theconnectors to be smaller, which also aids in reducing the size of themultiports disclosed herein.

FIGS. 33-47 depict views of another explanatory device 200configured as a multiport that comprises at least one connection port236 along with a securing feature 310 associated with the connectionport 236 that is similar to the multiport 200 of FIGS. 3 and 4 .

FIG. 33 depicts a partially exploded view of another multiport 200 thatis similar to multiport 200 of FIGS. 3 and 4 and has the optical fibers250 removed for clarity, and FIGS. 34-36 are views of the modularadapter sub-assembly 310SA of the multiport 200 of FIG. 33 . FIG. 37shows the modular adapter sub-assemblies 310SA of FIG. 35 being loadedinto the second portion 210B of the shell 210.

Like, the multiport 200 of FIGS. 3 and 4 , this securing feature 310comprises an actuator 310A and a securing member 310M with the securingmember 310M being a portion of a modular adapter sub-assembly 310SA forease of assembly and isolation of the retaining mechanisms so they canfloat independently. The securing feature member 310M of securingfeature 310 is suitable for retaining connector in connection port 236as discussed herein. Various different embodiments are possible forsecuring features 310 comprising more than one component for the devicesdisclosed.

Multiport 200 of FIG. 33 comprise one or more connection ports 236 andthe one or more securing feature passageways 245 as a portion of theshell 210. Multiport 200 of FIG. 33 comprises a shell 210 comprising abody 232 with one or more connection ports 236 disposed on a first endor portion 212 with each connection port 236 comprising a respectiveoptical connector opening 238. The optical connector openings 238 extendfrom an outer surface 234 of shell 210 into a cavity 216 and define aconnection port passageway 233. One or more respective securing featurepasssageways 245 extend from the outer surface 234 of the shell 210 tothe respective connection port passageways 233. A plurality of securityfeatures 310 are associated with the respective plurality of connectionports 236. As depicted, shell 210 is formed by a first portion 210A anda second portion 210B.

FIGS. 34-36 are views of the modular adapter sub-assembly 310SA of themultiport 200 of FIG. 33 , that is similar to the modular adaptersub-assembly 310SA used in the multiport 200 of FIGS. 3 and 4 . The maindifference in the modular adapter sub-assembly of FIGS. 34-36 are in thedesign of the adapter body 255. In this adapter body 255 the securingfeature resilient member 310RM is not capture in a resilient memberpocket of the adapter body 255. Instead, the second shell 210B comprisesa spring keeper 210SK adjacent to the respective connection port 236best shown in FIG. 37 . This may make the assembly of the multiport 200more challenging. Additionally, adapter body 255 of the multiport 200 ofFIG. 33 has different alignment feature 255Af on the bottom of theadapter body 255.

FIG. 37 is a top detailed perspective view of the modular adaptersub-assemblies of FIG. 35 being loaded into the second portion 210B ofthe shell 210 with the optical fibers removed for clarity. As best shownin FIG. 37 , the modular sub-assembles 310SA are individually placedinto the second portion 210B of shell 210 after the securing featureresilient member 310RM is place about the spring keeper 210SK. As shownthe alignment features 210AF of the second portion 210B of shell 210align the modular adapter sub-assembly 310SA with the respectiveconnection ports 236. In this embodiment, the alignment features 210AFare configured as a T-rail for seating the adapter body 255.

FIG. 38 is a detailed perspective view showing how the features of themodular adapter sub-assemblies 310SA of FIG. 35 engage the first portion210A of the shell 210 when assembled. FIG. 38 depicts a partialassembled view of multiport 200 of FIG. 33 showing the respectiveactuators 310A placed into securing feature passageways 245 within thefirst portion 210A of the shell 210 and the modular sub-assemblies 310SAbeing placed on the first portion 210A of the shell. This view is shownto depict the cooperating geometry between the modular sub-assembles310SA and the first portion 210A of shell 210. Like the other multiport200, first portion 210A of shell 210 also comprises alignment features210AF sized and shaped for cooperating with the alignment features255AFT on the top of adapter body 255 for securing the same when themultiport is assembled. The respective alignment features 210AF,255AFonly allow assembly of the modular adapter sub-assemblies 310AS into theshell 210 in one orientation for the correct orientation of the lockingfeature 310L with respect to the connection port 236. This view alsoshows that actuators 310A have a different geometry since they do nothave a completely round form-factor like the actuators 310A shown inFIGS. 19 and 20 . After the internal assembly is completed, the firstand second portions 210A,210B of shell 210 may assembled in suitablefashion using a sealing element 290 or not.

FIG. 39 is a detailed sectional views of the multiport 200 of FIG. 33through the connection port for showing the internal construction of themultiport with a fiber optic connector retained using the securingfeature 310. As shown in FIG. 39 , the connector mating plane 230MPbetween the ferrule of the rear connector 252 and ferrule of connector10 is disposed within the cavity 216 multiport 200 for protecting theconnector mating interface. Specifically, the respective ferrules arealigned using the ferrule sleeve 230FS. Connector 10 includes a lockingfeature 20L on the housing 20 for cooperating with a securing feature310 of multiport 200. This arrangement is similar for retainingconnectors 10 in the multiport 200 of FIGS. 3 and 4 . Connector 10comprises at least one O-ring 65 for sealing with the connector portpassageway 233 at a sealing surface when the connector 10 is fullyinserted into the connection port 236.

FIGS. 40A and 40B depicts the use of an input tether 270 with multiport200. The concepts disclosed may be used with the pass-through cables aswell. Input tether 270 has optical fibers 250 that enter the multiport200 and are terminated with to rear connectors 252 for making an opticalconnection at the connection port 236. In this embodiment, there is nosecuring feature for the input connection port 260. However, otherembodiments may retain the securing feature and secure the input tether270 from inside the device.

If used, input tether 270 may terminate the other end with a fiber opticconnector or be a stubbed cable as desired. For instance, the inputtether connector could be an OptiTip® connector for optical connectionto previously installed distribution cables; however, other suitablesingle-fiber or multi-fiber connectors may be used for terminating theinput tether 270 as desired. Input tether 270 may be secured to themultiport 200 in other suitable manners inside the multiport such asadhesive, a collar or crimp, heat shrink or combinations of the same. Inother embodiments, the input tether could be secured using a securingmember internal to the shell without the actuator as shown. The inputtether to multiport interface could also be weatherproofed in a suitablemanner. The input tether 270 may also have stubbed optical fibers forsplicing in the field if desired, instead of the connector 278.

Furthermore, the input tether 270 may further comprise a furcation bodythat has a portion that fits into the multiport 200 at the input port ofthe shell 210 such as into the optical connector opening 238 of theinput connection port 260, but the furcation body may be disposed withinthe shell 210 if desired as well. The furcation body is a portion of theinput tether that transitions the optical fibers 250 to individualfibers for routing within the cavity 216 of the shell 210 to therespective connector ports. As an example, a ribbon may be used forinsertion into the back end of the ferrule of fiber optic connector 278and then be routed through the input tether 270 to the furcation bodywhere the optical fibers are then separated out into individual opticalfibers 250. From the furcation body the optical fibers 250 may beprotected with a buffer layer or not inside the cavity 216 of themultiport 200 and then terminated on rear connector 252 as desired.

The input tether 270 may be assembled with the rear connectors 252and/or fiber optic connector 278 in a separate operation from theassembly of multiport 200 if the rear connectors 252 fit through theinput port. Thereafter, the rear connectors 252 may be individuallythreaded into the input connection port 260 of the multiport with theappropriate routing of the optical fiber slack and then have the rearconnectors 252 attached to the appropriate structure for opticalcommunication with the connection port passageways 233 of the multiport200. The furcation body may also be secured to the connection portinsert in the manner desired. By way of explanation, the input tethermay be secured to shell 210 using a collar that fits into a cradle. Thisattachment of the input tether using collar and cradle provides improvedpull-out strength and aids in manufacturing; however, otherconstructions are possible for securing the input tether.

FIGS. 41-43 depict various views of a mounting feature insert 200MFIthat may be attached to a portion of the shell 210 for securing thedevice such as with a band or tie-strap.

FIG. 42 depicts the mounting feature insert200MFI comprising insert openings 200IO disposed on opposite sides of acurved saddle for receiving a band or strap, and FIG. 43 is across-sectional view of the cooperation between mounting feature insert200MFI and the second portion 210B of shell 210.

FIGS. 44-46 depict various views of a mounting feature 298 that may beattached to the front end of the second portion 210B of the shell 210similar to the other mounting tab 298 disclosed. FIG. 44 depictsalignment protrusions 210AP on the front end 212 of second portion 210Bof shell 210 for securing mounting tab 298. Alignment protrusions areconfigured as T-rails in this embodiment, but other geometry ispossible. Specifically, alignment protrusions 210AP cooperate with aplurality of T-rail slots on mounting tab 298 as shown in FIG. 45 foraligning and attaching the mounting tab to the shell 210 of themultiport 200. Mounting tab 298 may be attached to the shell 210 asshown in FIG. 46 , and adhesive or fastener may be used as desired.Other variations of for the mounting tab are possible.

As shown in FIGS. 47 and 48 , multiports 200 may also have one or moredust caps 295 for protecting the connection port 236 or input connectionports 260 from dust, dirt or debris entering the multiport orinterfering with the optical performance. Thus, when the user wishes tomake an optical connection to the multiport, the appropriate dust cap295 is removed from the connector port 236 and then connector 10 ofcable assembly 100 may be inserted into the respective connection port236 for making an optical connection to the multiport 200. Dust caps 295may use similar release and retain features as the connectors 10. By wayof explanation, when securing feature 310 is pushed inward or down, thedust cap 295 is released and may be removed. Moreover, the interfacebetween the connection ports 236 and the dust cap or connector 10 may besealed using appropriate geometry and/or a sealing element such as anO-ring or gasket.
